Failure to profit from patterns of history

Denial of the lessons of history
Failure of opposing groups to appropriate the wisdom of the past
Perceived irrelevance of past experience
Historical research has failed to illuminate the patterns of history so that everyone may utilize the significant lessons of the past. People thus see no meaning in the past and are ignorant of their heritage. This isolates them in the present without an historical or a future context. The past needs to be viewed in such a way that people can understand who they are now and how best to move into the future.
